I just bought mine and this phone is good. No heating, no lagging or hang. All smooth, battery is good, using VOOC charger. Mine is 2gb, 16gb add 32gb micro sd. In malaysia Oppo shop is selling RM499.00
No worries, buy it.

Was a bit scared about the ram and rom.but it actually works very fine .and very fine display and superb rear facing camera along with a decent front facing camera.android Oreo out of the box phone works smoother.the biggest pro of this device is it's amazing battery life . Doesn't matter how heavily u use it .it will surely last for 2 days
